I can't find anyway to adjust the brightness on the head unit... looked through all the settings. Anyone know how to do this.
While playing around with things, I did find that I can start playing music in CarPlay Music, then go back to CarPlay home and hit the Pioneer menu option. From there, if I hit the icon for the iPhone media choice (not CarPlay), it gives me a really nice Pioneer screen with artwork and such. It seems to continue playing my CarPlay selected PlayList, but I'm not in CarPlay at that point. Unfortunately if I stay there, then other CarPlay stuff like navigation prompts don't show on the screen, although the audio prompts do. So I definitely have artwork if Pioneer can use it.
